The family kept the discovery to themselves for two years, but
then decided to enlist experts for help extracting the rest of
the mammoth skeleton.

Researchers from the University of Iowa identified the original
bone as the femur of mammoth. Since then they have uncovered the
mammoth's vertebrae and ribs, all of which John keeps in his
living room.

Archeologists and paleontologists are excited about the find
because it is unusual to find so many bones from a mammoth in one
place. However, since the bones were found on his property they
belong to John, who says he's not sure what he will do with them
yet.
